RICHARDSON COMPANY, OF PHILADELPHIA, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA SHIPPING CONTAINER 1 Application filed Oetober 24, 1 928. Serial No. 314,584.

My invention is an improved fibre board blank from which the flanged closure of my shipping container for the packaging of bulk improved container is formed; Fi 3 is an loads which must be securely but inexpenend view; Fig. 4 is a side view an Fig. 5 is sively sealed against sifting of the contents a top plan View of the box bent from the 5 0r ingress of dust or dampness. blank shown in Fig. 1; Fig. 6 is a bottom plan 55 3-? ed by the full width of the sealing substance convenient designations to distinguish be- 1 covering having flanges bent therefrom and 10 thereby provided with an internal continuous sealin surface on each side of the closure for su stantially the full width of each side,

ifiedin claim l'having the flanges inexpansiblyconnected by rivets.

4. A fibre board shipping containerasspec- 5. A fibre board shipping container comprisin a box having a peripheral surface forme by sides having extensions interiorly lapping the interior surfaces of adjacent sides, such adjacent sides being bent up from the bottom of the box and forming flaps proand affords a substantially, continuoussmooth viding a Smooth external sealing surface besealing surface complementary to and adapted to overlap and uniformly contact with the surface 10.

Shipping containers are usually filled with bulk loads, such as loose mint candy, to a point slightly below the top. In the utilization of my improved container, the surface 10 or 20, or both, may be coated with a sealing adhesive 21, the closure applied to the filled box and the container readily inverted. The

load, of course, falls upon the closure and forms an adequate resistance to the thrust of sealin rollers or plates between which the invertef container may be carried to firmly unite the adhesive surfaces 10 and 20.

By my improvements a tight and inexpensive container is provided particularly adapted for use with automatic sealing machines and which when" sealed cannot be readily broken open by the thrust of the load due to dropping etc..since such thrusts are resistinstead of merely by the thickness thereof.

- The terms sides and ends are not intended to designate any relation between the sizes of the respective parts but are merely tween the several box walls.

Having described my invention, Iclaim 1. A fibre board shippin container having sides bent upwardly rom the bottom thereof and forming a continuous sealing surface at the top of each side of'the box for substantially the full width of each side, thereby affording a substantially continuous smooth external sealing surface completely surrounding the mouth of the container and a each forming an internal continuous sealing surface on each side of the closure for substantially the full width of each side and affording a substantially smooth internal sealing surface contacting with said sealing surface first named, flanges aforesaid having .fiaps lapping and secured to the exterior sur- 60 faces of adjacent flanges and an adhesive uniting said sealing surfaces.

2. A fibre board shipping container as specified in claim 1 having the sides inexpansibly connected by rivets.

i 3. A fibre board shipping container as spec- .hin

the closure and the outer surfaces of the walls of the box formin complementary sealin surfaces on each si e of the container for su stantially the full width of such sides.

6. A fibre board shipping container comrising a blank creased to form grooves, memrs bent from said blank along said grooves and forming sides, and extensions on members aforesaid being slit from said blank along the edges of grooves aforesaid and having grooved portions, said extensions being bent within' adjacent members and having the grooved portions thereof engagedin the groove along which said member is bent.

7 A fibre board sbi ping container comprising a blank creased to form two pairs of transversely extending grooves, all of said grooves be ng approximately the same distance from the nearest edge to which they are respectivelyparallel, side members bent along grrooves aforesaid and having extensions slit om said blank alon edges of grooves aforesaid, said extensions fiaving grooved portions and being bent relatively to said side members and having their grooved portions seated in grooves aforesaid and end members bent teriorly said extensions, means inexpansibly securing said ends and extensions together, the side edges of the upper portions of said ends extending susbtantially to said side members and the'side and end members forming a smooth substantially continuous sealing surface, and a closure having flanges forming a smooth substantially continuous sealin surface engaging said surface first name flanges aforesaid having extensions exteriorly lappin adjacent flanges, and means for 1nexpansibly securing said extensions and adjacent flan es.

8. A fibre oard shipping container having a bottom with a side hinged to each edge thereof, said sides being connected at each corner of 'the container by an extension ged to a side and folded within and lapping adjacent side said last named sides being ing outer flaps; a closure havin a side hinged to each edge thereof, said si es being connected at each corner of the closure by an extension hinged to a side and folded over the exterior of and lappin an adjacent side; and means for inexpansib y connecting each of said extensions with the side which it laps, the inner surfaces of said closure sides and the outer surfaces of said container sides forming complementary sealing surfaces on each side of the container for substantially the full width of such side.

In testimony whereof I have hereunto set my hand this 18th da of October, 1928. MATHIEAS R. KONDOLF.
